Hippopotamus appears to be slow but they are actually pretty fast both on land and water. They run fast and they swim fast which is just what this viral video shows.

In this video that was published on YouTube Sunday shows a large, round hippo chasing after a speeding speedboat during a photo safari in Kasane, Botswana. It followed the boat around and at one point even got dangerously close to it.

According to African Wildlife Foundation, a hippopotamus can grow up to 13 feet long and 5 feet tall weighing up to 3.5 tons or 7,700 pounds. Hippos also kill nearly 3,000 people each year. However, people are also bringing hippos' population low each year by hunting them and pushing then out their natural habitats thus making their conservation status vulnerable.
